On-Line Transaction Processing
Network Remote Radio
MDS TransIt Series Overview
An MDS Transit system offers intelligent wireless networking products and network management software to support real time applications such as lottery terminals, ATM machines, POS terminals, water, gas and oil SCADA, etc. The Transit On-Line Transaction Processing (OLTP) system is a highly efficient wireless implementation that employs intelligent radios at each end of the wireless network. A Transit point-to-multipoint system is organized in cells. Each cell consists of one NM-200 master station and multiple NR-100 remote radios managed by Transit NMS (Network Management System) software. Multiple master stations are typically connected through a WAN to one or multiple processing centers.
Transit integrates into existing customer networks allowing the wireless network to seamlessly coexist with a wired network infrastructure. It provides intelligent network support for real time applications with a data transfer rate of up to 19.2 Kbps.
MDS TransIt NR-100 Product Overview
The Transit NR-100 family of radios utilizes DSP technology to offer a highly efficient radio network with extended range capability to support bursty data applications.
Transit NR-100 is based on our reliable family of licensed narrowband radios (200 MHz to 960 MHz) and unlicensed spread spectrum radios (900 MHz) that have made GE MDS a leader in the wireless industry.
The Transit NR-100 is a wireless remote transceiver that supports most standard networking protocols.
The NR-100 single port can be remotely configured via software to run one of many synchronous or asynchronous serial protocols as well as IP over Ethernet1.
The proprietary WARP radio protocol runs simultaneously and independently from the user data port protocol. The WARP radio protocol ensures fair and immediate network access to all remotes sharing the wireless media. It also has the functionality required to provide a reliable data delivery service in a potentially noisy radio environment. With its collision avoidance mechanism WARP virtually eliminates unnecessary retries and maximizes user data throughput.
When a polled protocol is configured on the user data port a spoofing mechanism prevents propagation of empty polls across the radio network thus saving transmission resources for actual data traffic.
Why Consider a MDS TransIt Solution?
- Carrier-rated reliability that supports mission critical revenue producing applications. GE MDS is an ISO 9001 certified manufacturer of radio equipment.
- Transit NM-200’s architecture offers a redundancy option at the master station for increased availability.
- Transit NMS monitors every point on the network. With a Windows-based GUI it offers complete control and updated information to manage the network: alarms, statistics, diagnostic tools and remote control functionality.
- Ease of integration – Transit is compatible with standard WAN transport protocols. Its multiprotocol capability encompasses the most comprehensive suite of protocols.
- Efficiency – Transit operates on a single radio frequency allowing you to double the number of networks running on existing frequency pairs or to cut in half the expense to acquire new frequency pairs. Its multiprotocol capability reduces the need to support parallel networks for different services.
- Rapid deployment – reduces time to revenue.
- Flexibility to incorporate both licensed and license-free (spread spectrum) radios in the same system.
